Leloir pathway

Biology; Biochemistry

The metabolic route by which galactosyl and glucosyl units are interconverted; the transformation of galactose and ATP to glucose-1-phosphate via the galactokinase, galactose-1-phosphate ...

A non-peptide synthetic molecule that reproduces some features of a natural peptide, e.g. it may bind strongly to an antibody by placement of the same functional groups, in the same relation to each ...

High efficiency particulate air philtre (HEPA filter)

Biology; Biochemistry

A mat of fibres, e.g. fibreglass, that is designed to block airborne particles of 0.3 Âµm or greater with an efficiency of at least 99.97%. Among their applications is the prevention of contamination ...

Affinity chromatography

Biology; Biochemistry

The separation of soluble macromolecules by use of a stationary phase that is designed to interact specifically with, and thus retard the elution of, the desired material; e.g. a hapten attached to a ...

Cryptic

Biology; Biochemistry

Descriptive of a function that is not usually, or not always available or expressed; e.g. an enzyme that is separated from poteintial substrates by being located in a lysosome, a splice site in a ...

Transformation

Biology; Biochemistry

The process by which a cell line, that can normally be expected to undergo a limited number of cell divisions before death, becomes immortal; also the process by which isolated foreign DNA is ...

Imposter

Biology; Biochemistry

A gene product that can replace a missing homologous protein. Knockout experiments are sometimes misleading because a physiological function is preserved by an imposter; in such cases, a lethal ...
